【中文标题】GIT 致命：模棱两可的参数“HEAD”：未知修订版或路径不在 Travis 的工作树中

【英文标题】：GIT fatal: ambiguous argument 'HEAD': unknown revision or path not in the working tree in Travis

【发布时间】：2016-09-15 04:44:10

【问题描述】：

我有以下配置：

git version 1.8.5.6
GNU bash, version 4.2.25(1)-release (x86_64-pc-linux-gnu)

我打电话给zgit_info_update 并尝试提交。但是在 Travis (Git diff command returns error #6069) 中从 Bash 运行 git diff --name-only dev 时我仍然遇到问题。

我怎样才能让它工作？

这里是输出：

Use '--' to separate paths from revisions, like this:

【问题讨论】：

暗中刺伤：先试试git pull ing？

【参考方案1】：

更简单的解决方法是

git remote set-branches --add origin $BRANCH_TO_DIFF_AGAINST
git fetch
git diff origin/$BRANCH_TO_DIFF_AGAINST

解释一下。例如，想法/要点是什么？为什么它可以解决问题？请通过editing (changing) your answer 回复，而不是在 cmets 中（without "Edit:"、"Update:" 或类似的 - 答案应该看起来像是今天写的)。

这和defrex's comment on the issue on GitHub非常相似。

【参考方案2】：

使用以下命令解决了该问题：

if [ "$TRAVIS" == "true" ]; then
  # Resolving `detached HEAD` by attaching HEAD to the `TRAVIS_FROM_BRANCH` branch
  TRAVIS_FROM_BRANCH="travis_from_branch"
  git branch $TRAVIS_FROM_BRANCH
  git checkout $TRAVIS_FROM_BRANCH

  # Fetching `TRAVIS_BRANCH` branch
  git fetch origin $TRAVIS_BRANCH
  git checkout -qf FETCH_HEAD
  git branch $TRAVIS_BRANCH
  git checkout $TRAVIS_BRANCH

  # Switch to `TRAVIS_FROM_BRANCH`
  git checkout $TRAVIS_FROM_BRANCH
fi
